Recently, with the support of the National Natural Science Foundation of China, the HIT Youth Talent Plan and the HIT Cultivation of ExcellenceFoundation Researcher Project, Professor CHEN Guanying from the School of Chemical Engineering and Technology published, “Light upconverting core–shell nanostructures: nanophotonic control for emerging applications” in thewell-known, international journal, Chemical Society Reviews (Impact factor 30.425 in 2013).
This review is the first time a researcher has illustrated the use of luminescent dynamics behavior concepts of modulation nuclear shell structurenano-photonics upconversion nano-crystals. Additionally, how to use chemical conversion on controllable nano-crystal shell structures in a single atomic layer precision achieve growth was described. In recent years there has beenimportant progress in this area, including, the core-shell structure of upconversion nano-crystals in multimodal imaging, solar cells, infrared anti-counterfeiting, and fingerprint detection. Put forward the original opinion and discuss the future development direction and trend of rare earth nano-fluorescent bio probe.
Rare earth doped upconversion nano-crystals are multiphotonnano-materials which can realize visible or UV light excitation in weak, short wavelength emissions. It has chemical stability, is non-toxic, line - narrow, has along fluorescence lifetime, high luminous efficiency, tunable fluorescence emission and other advantages. Currently it has good application prospects in deep tissue imaging, imaging of single disease molecules inside the human body, photodynamic therapy, drug controlled release, and highly efficient solar cells.How to build efficient multi upconversion rare earth nano-crystalline and further quantitative analysis are the current research hotspots in the field of nano-materials.
Professor CHEN Guanying has long been engaged in the design of light emitting upconversion materials research and application. He has studied such areas as controllable modulation structures, high efficiency ultra-size conversion fluoride nano-crystals and the kinetics of luminescence mechanisms, high contrast near infrared and near infrared Stokes biological imaging, and heterogeneous nuclear shell structure enhancement on the conversion efficiency of nano-crystalline luminescent. Early in 2013, Professor CHEN published a series about materials research and design in the internationaljournal, ”Accounts of Chemical Research” (Impact factor 24.328 in 2013). In2014, he was invited to publish a review article about the application of upconversion nano-crystals in the biomedical field and his report washighlighted on the cover of the journal, “Chemical Review” (Impact factor 45.661 in 2013).
Chemical Society Reviews publishes critical reviews written by experts in related fields and has strict standards for examining and approvingmanuscripts. The articles are updated and improved during the writing, sending, and editing processes. According to the introduction, the publishing ofthis article shows that HIT has moved to the top in the field of design andapplication of upconversion luminescence materials, and has attracted theattention of international scholars.
